Each carnage is provided with suitable means for movlng it and the water wheel carried thereby into and out of operative position, as by a backwardly extending rack 15 en- 'gaged by a pinion 16 whose shaft 17 car: ries a worm wheel 18 engaged by a worm 19.

20 denotes a driving shaft shown as mounted in bearings secured to pillars 21. This shaft may extend the entirelength of the face of the dam and to a dynamo or other machine to be driven. The driving shaft carries a series of sprocket wheels 22 which are connected by sprocket chain 23 with similar sprocket wheels 24 on the shafts 25 of the water wheels. 7

In the form illustrated in Fig. 3 I have shown a dynamo 26 mounted 'on the carriage with the water wheel. a

28 denotes swinging deflectors hinged as at 29 to the face of the dam which may be used to regulate the volume of water coming in contact with the water wheels and are entirely concealed by the falling water. When a water wheel is to be removed or repaired, the corresponding deflector may be swung outward to carry all of the water away from the wheel so that it may be examined or repaired without moving it out of operative position. These swinging deflectors may be operated in any ordinary or preferred manner as by hydraulic or pneumatic power or steam.

Be it known that I, WILLIAM H. BAKER, a citizen of the United States, residing at Bridgeport, county of Fairfield, State of Connecticut, have invented an Improvement in Dams and Hydraulic-Power Transmitters, of which the following is a specification.

This invention has for its object to utilize to the greatest possible extent the dynamic energy of a water fall without in any way detracting from the scenic beauty or grandeur of the falls, and the invention consists of the precipice over which the water passes in the form of a dam and providing in the face of the dam chambers for water wheels with means for moving the water wheels into and out o operative position independently, means for connecting the water wheels independently with a driving shaft and means for deflecting the water so asto utilize to the maximum extent the energy of the falls.

With these and other objects in view I have devised the novel dam and power transmitting means of which the following description in connection with the accompanying drawings is a specification, reference characters being used to indicate the several parts.

Figure 1 is a section of the dam on the line l-1 in Fig. 2 looking in the direction of the arrows showing power transmitting means in one of the chambers; Fig. 2 a front elevation of the face of the dam showing a series of water wheels and deflectors; and Fig. 3 is a detached view illustrating a form of the invention in which a dynamo is mounted on a carriage with a water wheel.

My invention requires that a portion or all of the water be deflected from its normal channel so that the entire crest of the precipice may be built-over in the form of a from the face of the dam to prevent the dan- Carriages 13 carrying water wheels 14 are ger of injury to the water wheels.

Between the water wheels I place perma- 10 denotes the dam which extends from nent deflectors 34; which protect the mountthe base to the top of the precipice and efings of the water wheels and turn the water fectually protects it and prevents wearing falling between the wheels inward upon away. This dam is provided in its face at them so that practically the entire volume of or near the base with chambers 11'; which water passing over the dam may be turned are suitably shaped to meet the requireupon the wheels and its energy utilized.

ments of the special conditions involved. 35 denotes ice guards which are rigidly se- Within each chamber are tracks 12 which cured to the crest and the face of the dam lead out in front. of the face of the dam. and .act to carry cakes of ice far enough 36 denotes arms pivoted as at 39 tothe ice guards, which, in winter, are turned over backward, as indicated by dotted lines in Fig. 1 and liein channels 37 in the crest of the dam,-in which the upper ends of the ice guards are secured. When there is no ice in the river these arms may be swung downward, as shown in full lines in Fi and 2, in which position they rest upon shoulders 38 on the ice guards, and may be used as 'supportsfor a walk or bridge 40 for observation purposes below the brink of the falls and beyond the water.

Having thus described my invention, I claim:

1. A- structure of the character described comprising a dam for protecting the crest and face of a precipice, said dam having a chamber built therein, a carriage-in said chamber, a water wheel mounted on the carriage, means for moving the carriage and wheel into'and out of operative position and a swinging'deflector to regulate the amount of water that can come in contact with the wheel.

2. A structure of comprising a dam for protecting the crest and face of a precipice, said dam having a chamber built thereln, a carriage in said chamber, a water wheel mounted on the carriage, means for moving the carria e and wheel into and out of operative posltion, a swinging deflector to of water that can come in contact with the wheel and deflectors on the wheel which turn the water in upon it.

3. A structure of the character described comprising a dam for protecting the crest and face of a precipice, said dam having a swinging deflector and chamber, a water tecting the crest the character described regulate the amount m the opposite sides of" chamber built therein, chamber, a water wheel riage, means for wheel into and out of operative position, a a cylinder, piston the deflector, for the a carriage in said mounted on the carand toggle for moving purpose set forth.

4. A structure ofthe character described comprising a dam for protecting-the crest and face of a precipice said dam having a chamber built therein, a carriage in said wheel mounted on the carriage, and a rack and pinion'for' moving the carriage into and out of operative position.

5. The combination with a damfor proand. face of a precipice, said dam having av chamber in its face, of a water wheel in said chamber, a swinging deflector for the purpose set forth and ice guards secured to the crest and face of the dam for protecting the wheel.

6. The combination tecting the crest and face of aprecipice, said dam ving a chamber in its-face, of a water wheel in ,said chamber, a swinging deflector for the purpose set forth, ice guards secured to the crest and face of the dam and arms pivoted to said guards which are adapted to be swung backward out of the way or forward of the guards and a bridge supported by said arms when in operative position.

In testimony whereof I affix my signature presence of two witnesses.
